IMAGE DECODING METHOD AND IMAGE DECODING APPARATUS

摘要

In order to provide an image encoding technology that reduces the amount of encoding, in an encoding apparatus that encodes layers having a plurality of resolutions into one stream, adaptive and efficient video compression is performed by determining the coding unit, the prediction unit, and the transform unit of a layer with reference to the coding unit, the prediction unit, and the transform unit of a lower layer according to respective predetermined rules and by switching the determined rules with flags.
